Embodiment

Disclosed herein is that the service that can be used for Internet of Things (IoT) is usually provided using one or more service units.Often A service element can be provided by multiple equipment or virtual unit (service element host).It is discussed in detail herein to be and service The associated concept of layer, such as service, service host, service element and service element host.Service is considered client Set interested, function or data are held, and is arranged to client-based input and one composition fruit and delivery is provided Thing.Service host is that the entity of interface can be provided with advertisement service and for client access service.Service host can be from service Element, which is formed, entirely to be serviced and passes it to service request source.Service element is considered single group of composition service Part.Service element is typically the data (for example, data from physical world sensing) for being used to provide service.For example, service element Can be temperature or blood glucose level data.Service element can correspond to major function (such as the temperature from thermometer of particular device Degree), or can be by having the function of multiple equipment (such as moving equipment) generation.Mobile equipment can be utilized in sensor One or its combination sense light, movement, orientation or touch etc..Finally, service element host can be defined as service element Physical host.Multiple and different service element (such as temperature or humidity) can be located on a service element host. For example, weather service includes temperature as one of its service element；In this way, temperature sensor node will be service element host.

Fig. 4 shows that the weather for including the use of service element speculates the service condition of service.In Fig. 4, neighborhood 130 includes Service element (such as temperature, humidity and CO2) and corresponding service element host, such as temperature sensor 131, humidity sensor 132 and CO2 sensors 134.Weather speculates that service host 133 can be based on from various equipment (for example, those service elements master Machine) collect data generation speculate, and to miscellaneous equipment provide service.

For example, with reference to figure 4, thus it is speculated that can be weather good or not in neighborhood 130, this can be based on by being deployed in neighborhood 130 In various sensor devices collect temperature, humidity and CO2 (for example, air pollution) data.As shown in figure 4, various sensings Device deployed with devices is in neighborhood 130, for sensing each parameter, such as temperature, humidity and CO2.The particular weather speculates service With gateway 133, gateway 133 is service host.Weather speculates service element of the service with three types, each service element With multiple main frames (for example, various sensors).

Traditionally, the function for the service (as defined herein) for supporting to be made of multiple service elements is lacked.Traditional clothes Business layer (for example, oneM2M service layers) does not have this service concept, and it does not support service can be by multiple service elements The scene of composition.Traditional services layer defines many resources, but these resources only store the data collected from physical world.Client End can retrieve data and processing locality it.In addition, traditional service layer does not provide processing and maintenance can be by multiple clothes The method of the information of the service of business element composition.If without these methods, can not just be found in service layer or using service.

As discussed herein, service that (it is unlike regular service to determine information based on the data collected by service element Layer only stores data like that).Service disclosed herein can use the data provided by sensing physical world.This new demand servicing It can be provided by service layer, this enables the client to find and using service.Serviced herein for example with reference to disclosed in figure 4, can be with Speculate weather good or not or on 130 weather good or not of neighborhood.Another example is associated with blood pressure data.It can provide really Whether whether a fixed people health or need the service of any medicine.

Following public is the method that service layer provides the ability for supporting the service with multiple service elements, and is directed to The concept proposed uses the oneM2M examples that oneM2M is realized.It should be appreciated that perform step shown in Fig. 5-Fig. 7 and Figure 10-Figure 11 Rapid entity is logic entity, it can use equipment, server or the department of computer science being stored in shown in such as Figure 14 C or Figure 14 D The form for managing in the memory of system and at which the software (for example, computer executable instructions) performed on device is realized.That is, Fig. 5- Method shown in Fig. 7 and Figure 10-Figure 11 can use the equipment or computer system being stored in shown in such as Figure 14 C or Figure 14 D The form of software (for example, computer executable instructions) in the memory of computing device is realized, when the processing by computing device When device performs, which performs the step shown in Fig. 5-Fig. 7 and Figure 10-Figure 11.In one example, into one Details is walked below in relation to described in the interaction of M2M equipment, the service host 141 of Fig. 5 may reside within the M2M gateways of Figure 14 A In equipment 14, and the service layer 142 of Fig. 5 may reside within the M2M equipment 14,18 or 22 of Figure 14 A.

It is exemplary that Fig. 5 is shown with servicing, service element and host report (hereinafter referred to as S-SEaH reports) are associated Message flow.Service layer 142 obtains the input of this S-SEaH reports, to establish service, service element and service for each service Element host record.As discussed herein, service and be made of one or more service elements.Can be respectively each service and Each service element distribution serviceID (service ID) or elementID (element ID).

With reference to figure 5, in step 144, service layer 142 receives the S-SEaH report message that may be from service host 141.Table 1 provides the example that may be embodied in the content in S-SEaH report message, particularly when new demand servicing can use.
